#Chapter 2

If we are given a simple portrait puzzle, its outline is rectangular, composed of 8X8 in total 64 pieces.

Then, after learning the final image-forming information of the puzzle, there are roughly three ways of thinking:

The first idea is to solve the parts first, and then piece together the parts and parts. If it comes to portrait puzzles, such as spelling out the head, hands, feet, etc., and then connecting the head, hands, feet and torso together. This is a normal logical order.

The second idea is the order method, which continues to deduce it in one direction, such as starting from the head, to the neck, and then to the upper body...

The third type is that because you already have a picture in your heart and have virtualized the rough position of each piece on the desktop, then put the tiles in your hand into it in turn, put the nose on the nose and the feet on the feet. It seems that each piece has no connection. When all the pieces are placed, the puzzle of the character has been completed.

This third method of "calling the numbers" is obviously a genius.

The example of the portrait puzzle is really simple, and the plan expansion diagram of Li Fan's polyhedral is definitely not a square rectangle. The 34 faces that make up the polyhedral are spread out in various shapes and angles.

In principle, if Li Fan hadn't teamed up like this today, hundreds of millions of viewers might have seen such operations.

Because, normal people don’t do this! Even the simplest portrait puzzle, I have never seen anyone use this method to do puzzles, let alone the plane expansion diagram of this difficulty level!

Then, all the audience was stunned, excited, and dumbfounded in the utter incomprehension!

Sun Feifei patted her chest and said, "It's so amazing, there's such an operation!"

Doctor Chen said excitedly: "When designing this question, I never thought that there would be such a grouping method. This is an idea that is not within the logic of normal people's thinking!

What is the most powerful brain? Therefore, I will give you a new definition, which is to use incredible methods to solve complex problems. This is the most powerful brain!"

Jia Yun quickly interrupted: "Please don't be excited, everyone, be quiet first, be quiet!

We are relay races. The competition has not been completed yet. We need to verify the correctness and error of Li Fan immediately! You have delayed Haha Girl Team for one minute!

Please verify the results of the staff!”

The staff entered the number of each picture into the computer in order, and the verification was completed instantly. She whispered: "Correct!"

Doctor Chen clenched his fist hard, and Li Fan did not disappoint him.

Jia Yun said: "Please pass the information on the plane expansion diagram to the relay player Miaomiao!"

The staff handed a tablet computer to Miaomiao. There were 34 numbers in this tablet computer, that is, the sum of the numbers on each of the 34 faces of the plane expansion diagram: 4, 2, 3, 5, 3...

This challenge project of "Looking for It" consists of two parts: "Jigsaw Puzzle" and "Super Computing".

The "Jigsaw Puzzle" process that Li Fan is responsible for has been completed, and next, Miaomiao needs to relay the "Super Computing" part.

The moment Miaomiao took off her tablet, she was instantly happy and thought to herself: It's so simple, the numbers are basically below 5!

She held the tablet and ran to the writing board quickly, picked up her pen and started writing quickly.

Time passed quickly, and Niu Bige, who was standing beside Miaomiao, was already anxious and eager to see him. He suddenly shouted to Lin Xiaofeng: "Just make a correct answer, you don't need the best solution. As long as your answer is correct, I can solve it for you!"

"Ah? Are you sure?" Lin Xiaofeng said in confusion.

"I'm sure, don't forget that I'm-" Niu Bige originally intended to say, "Don't forget that I have 18 national patents." But after he glanced at the listless Li Fan not far away, he decided not to brag. He immediately changed his words, "Don't forget that I am your strongest backing!"

Lin Xiaofeng nodded affirmatively, "Okay, I'll make an answer as soon as possible!"

Niu Bige was surprised when he heard this. It turns out that you haven’t even made a single answer yet. Dear?

Miaomiao was very calm at this time. It has been 15 minutes since she received Li Fan's data.

Within these 15 minutes, she completed the calculations and conducted two checks.

Her aftertaste glanced at Niu Bige who was "unemployed" beside her, and then paid attention to Lin Xiaofeng who was busy not far away, then forced herself to start the third inspection...

Two minutes later, Lin Xiaofeng finally ran to the challenge area and made up her answer. After verification by the staff, a tablet computer with data entered was handed over to Niu Bi Singer.

Niu Bige glanced at the data and was stunned:

11, 9, 11, 12, 10... Among these data, there are only a handful of single digits, but there are basically fewer of Miaomiao's data in the set of data!

Lin Xiaofeng also clenched his fists at him, "You can do it!"

Niu Bige breathed out and thought to himself: This is a big deal, sister!

Niu Bige just lifted up his pen, but saw Miaomiao around him raise his hand and whispered: "Referee, I'll complete the challenge!"

On the answer board, the answer to "≈39.375218" is clearly in sight.

The referee said: "Please wait a moment, and we will finally reveal the answer together."

This wait is 15 minutes.

Niu Bige finally put down his pen, took a deep breath, raised his hand and said, "I'm done!"

On the writing board, the final answer is: ≈109.1393832

Jia Yun said: "Okay, is it Niu Bige right or Miaomiao right? Please ask the science assistant to come over and let us witness it together!"

The two science assistants brought two answer boards respectively. Jia Yun walked to one of the science assistants first, and she said, "This is the final result of the Lei Ge team. Can the numbers in this brand be consistent with Niu Bige's answer? Please see!"

hiss!

Jia Yun pulled out the answer board, and the mathematics hidden in it was revealed: ≈109.1393!

"Correct! Congratulations to Lei Ge team, the answer is correct. Next, the life and death rights of Lei Ge team fall into Miaomiao's hands. If Miaomiao's answer is correct, it will win because Miao Hahamei team takes a shorter time.

Next, let’s verify Miaomiao’s answer, count down to 3 words!”

The audience really cooperated and shouted:

“3!”

“2!”

“1!”

hiss!

The answer board is pulled open, revealing the correct answer inside: ≈39.3752

Haha, the sister team was filled with joy. Miaomiao slammed Li Fan excitedly and shook Li Fan's arm a few times, "It's so powerful, Li Fan, you're so powerful!"

Jia Yun said: "Why is Miaomiao so excited?"

Miaomiao said convincedly: "I am really convinced. My set of data is so good. The numbers are basically below 5. It is much simpler than Niu Bige's set of data. Li Fan is so good!"

Doctor Chen said: "That's what I said. The correct answer in the first round is not important. What matters is the optimal solution in the correct answer.

Li Fan's set of data is very small. If it is substituted into a specific formula, Miaomiao's calculation is not large, while Niu Bige's set of data is countless times more complicated than Miaomiao's!

This is the mutual cooperation of relay competitions, and this is the extremely important side of the optimal solution.”

Jia Yun asked, "Then is the optimal solution for this set of data from Li Fan? Please explain it to everyone!"

Doctor Chen stood up and said, "First of all, I don't know if Li Fan's answer is the best solution. Please look at the big screen first!"

On the big screen, countless arrays of data were scrolled out:

(11,5,6,2,9…3)

(7,6,3,9,10…6)

...

(9,8,8,4,11…5)

(Note: In the braces, all numbers are 34, because the plan expansion diagram of Li Fan's project is 34 faces, so there are 34 "sum of numbers".)

After scrolling the big screen for a while, Doctor Chen used a remote control pen to scan the big screen and said, "Please note that the countless data you see are all the first part of this project, the answer to "Jigsaw Puzzle"!"

There were bursts of exclamations in the hall: "Wow!"

"Oh my God!"

"How many answers do you have to do!"

...

"The audience asked how many sets of answers there are. OK, I tell you, please see," Doctor Chen clicked the remote control pen, and an illustration appeared on the big screen. He began to explain to the audience:

"Let's take a triangle as an example. The plane expansion diagram of a triangle is composed of 4 triangles. If the first triangle face may be composed of 3 schemes, the second triangle face may be composed of 2 schemes, the third face 3 and the fourth face 4.

Then, the correct answer to the plan expansion diagram of this triangle is: 3X2X3X4=72! There are 72 types in total!

As for the project Li Fan challenged, everyone looks at the big screen, and there are 34 aspects in total. How many answers are there?

2X1X2X2X1X3X1...X2=    65536 types, a total of 65536 answers!

With more than 60,000 answers, imagine how difficult it is to lock the optimal solution from more than 60,000 answers, it is definitely not something that humans can do!

And Li Fan’s answer is the optimal solution given by the system? Is it true? Please see!"

Press the remote control pen again, and a set of data appears on the large screen: (4, 2, 3, 5, 3...3)

Jia Yun picked up the tablet and said, "Now we will check Li Fan's answer with the answer to the optimal solution given by the system.

The first, 4, correct!

The second, 2, correct!

The third one, 3, correct!

…”
